What it is
The Ariston NTC cable, part number 65116890, is the temperature sensor lead used on Ariston CLAS System ONE and E-System ONE appliances. It connects the NTC sensor to the boiler's control PCB, allowing the board to read temperature and regulate operation accordingly. A faulty lead affects the signal the PCB receives, which can disrupt heating and hot water delivery.
Signs this part needs replacing
- Temperature readings that are erratic, implausible or frozen on the display
- Boiler lockout or fault codes linked to the temperature sensor circuit
- Heating or hot water running at the wrong temperature despite correct settings
- Visible damage to the cable, insulation or plug connector
- Intermittent faults that appear when the cable or connector is disturbed
Before you order
- Confirm your appliance model against the fit list above before ordering
- Check the existing cable and connector for damage, corrosion or poor contact
- Verify the fault is traced to the sensor lead rather than the sensor itself or the PCB
- Have the appliance model and serial details to hand when checking compatibility
